# Re: st: local macro with if qualifier

How about:

local i=`i'+(d31b_`i'!=d31b_`y' & d31b_`i'==0 & `y'<3)

?

hth,

```Dear all,
how can i use a local macro with the if qualifier option?
Unfortunately, this code doesn't work:

local i=`i'+1 if d31b_`i'!=d31b_`y' & d31b_`i'==0 & `y'<3

Thank you in advance.

The full code is:

gen amico=0
local i=1
set trace on
forval y=2/3 {
replace amico=`i' if d31b_`i'!=d31b_`y' & d31b_`i'==1 & `y'==3
replace amico=`i' if d31b_`i'==d31b_`y' & d31b_`i'==1 &
d31c_`i'>d31c_`y' & `y'==3
replace amico=`i' if d31b_`i'==d31b_`y' & d31b_`i'==1 &
d31c_`i'==d31c_`y' & d31d_`i'>d31d_`y' & `y'==3
replace amico=`i' if d31b_`i'==d31b_`y' & d31b_`i'==1 &
d31c_`i'==d31c_`y' & d31d_`i'==d31d_`y' & `y'==3
replace debug=1 if d31b_`i'==d31b_`y' & d31b_`i'==1 &
d31c_`i'==d31c_`y' & d31d_`i'==d31d_`y' & `y'==3

replace amico=`y' if d31b_`i'!=d31b_`y' & d31b_`i'==0 & `y'==3
replace amico=`y' if d31b_`i'==d31b_`y' & d31b_`i'==1 &
d31c_`i'<d31c_`y' & `y'==3
replace amico=`y' if d31b_`i'==d31b_`y' & d31b_`i'==1 &
d31c_`i'==d31c_`y' & d31d_`i'<d31d_`y' & `y'==3
replace amico=`y' if d31b_`i'==d31b_`y' & d31b_`i'==1 &
d31c_`i'==d31c_`y' & d31d_`i'==d31d_`y' & `y'==3

local i=`i'+1 if d31b_`i'!=d31b_`y' & d31b_`i'==0 & `y'<3
local i=`i'+1 if d31b_`i'==d31b_`y' & d31b_`i'==1 &
d31c_`i'<d31c_`y' & `y'<3
local i=`i'+1 if d31b_`i'==d31b_`y' & d31b_`i'==1 &
d31c_`i'==d31c_`y' & d31d_`i'<d31d_`y' & `y'<3
}
